I believe when t he ignition switch is in the "on and Start" positions power is supplied to the coil terminal B+ through a light blue/black wire. On the D terminal of the coil the signal wire for the tachometer is a brown wire . I think there is also a second brown wire on that terminal that goes to the ignition control relay.

Thanks for the input - I pulled the coil out a few months ago... and totally forgot to take a picture of the wire setup. At the moment it didn’t matter because the harness was a complete mess. I now have removed all the electrical tape and cleansed it up.. to where it’s only the factory colored wires.

Power from for the ignition - in my case blue wire with black stripe and brown wire to the tach.
